These are 58 minutes of subs at 30s and 60s from last night.  One is done without the comet registration and the other with. Worked good for me. Just wondering how others got the stars to not trail when using the comet registration. A bit confused, but thanks for great update, looks much better after the comet registration

neo lpc cbg mod SC St
neo MONO session 1 lpc cbg mod cbg csc SC St

. Still learning.

Interesting result on the right indeed, but great to see APP working here. 🙂 In a follow-up version you will be able to remove the trails better, but people now use aggressive outlier rejection for that, sigma clipping.

Thanks, i watched the video again and was able to try the aggressive rejection and it did work. However still new at this and learning.

Hi. I've just had a play with the Beta Comet stacking, here are my results... These were 25 20 second images with Hypercam 183C ProTec and Starwave 80ED. Couldn't get the light pollution tool to work though...

What didn’t work with the LP tool?

@vincent-mod Hi. I could not process out the orange light from light pollution that was affecting my view of the Comet. No idea why? Tried a few times. Always happy for any advice.

Should be possible, maybe it does then affect the faint comet tail, which can be a negative thing about it in this case. I would need your data to try myself, if you want you can upload it to our server;

Go to https://upload.astropixelprocessor.com and use upload1 (or upload2 till 5) as username and password will then be the same as the username.

Create a directory named “charles-thody-orangebackground” and upload in there. Thank you!

Ok so to me the data looks really good. Also after LP, I'm not seeing light pollution to be honest.
